{{main|Marcos TSO}}
The [[Marcos TSO]] was launched in 2004 with a [[Chevrolet small-block engine|Chevrolet V8]] engine in either {{convert|350|bhp|kW PS|0|abbr=on}} or {{convert|400|bhp|kW PS|0|abbr=on}} versions. The car's components were [[Computer-aided design|CAD]], designed in England and its chassis engineering was completed by [[Prodrive]].  These vehicles were produced by Tony Stelliga of Marcos.

Also in 2004, the 5.7-litre [[Chevrolet Corvette]] ([[GM LS engine|LS1]]) V8 TSO GT was announced, but solely for the Australian market. It was joined in 2005 by the GT2 for the European market.

In 2006 Tony Stelliga announced the TSO GTC, a modified version of the current TSO with a racing suspension, racing brakes and a rear diffuser. The car continues on with its [[Chevrolet]]-sourced {{convert|420|bhp|abbr=on}} V8, but there was also a {{convert|462|bhp|abbr=on}} Performance Pack available as well. With the extra power from the Performance Pack the TSO GTC accelerated to {{convert|60|mi/h|km/h|abbr=on}} in 4.1 seconds and to {{convert|100|mi/h|km/h|abbr=on}} in 8.5 seconds. With the bigger {{convert|340|mm|in|abbr=on}} [[AP Racing]] brakes, the TSO GTC delivered a 0–100–0 time of 12.9 seconds, and the extra power allowed it to accelerate from 50 to {{convert|70|mi/h|km/h|abbr=on}} in just 2.1 seconds. Its top speed was over {{convert|185|mi/h|km/h|abbr=on}}.

2 prototypes and 7 production models cars exist.  Tony Stelliga's company went into liquidation in October 2007.
